An electric wire includes a conductor having a cross-sectional area of not less than 225 mmand not more than 275 mm, an insulation provided so as to cover the outer periphery of the conductor, and a wire sheath provided so as to cover the outer periphery of the insulation. The amount of deflection is not less than 130 mm when, at 23&#xb0; C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at &#x2212;40&#xb0; C.

Electric wire and cable

An electric wire includes a conductor having a cross-sectional area of not less than 290 mmand not more than 360 mm, an insulation provided so as to cover the outer periphery of the conductor, and a wire sheath provided so as to cover the outer periphery of the insulation. The amount of deflection is not less than 120 mm when, at 23&#xb0; C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at &#x2212;40&#xb0; C.

An electric wire includes a conductor having a cross-sectional area of not less than 180 mmand not more than 220 mm, an insulation provided so as to cover the outer periphery of the conductor, and a wire sheath provided so as to cover the outer periphery of the insulation. The amount of deflection is not less than 180 mm when, at 23&#xb0; C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at &#x2212;40&#xb0; C.

An electric wire includes a conductor having a cross-sectional area of not less than 135 mmand not more than 165 mm, an insulation provided so as to cover the outer periphery of the conductor, and a wire sheath provided so as to cover the outer periphery of the insulation. The amount of deflection is not less than 250 mm when, at 23&#xb0; C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at &#x2212;40&#xb0; C.

A submersible motor electric wire includes a conductor including a copper wire and an enamel coating formed on the periphery of the copper wire, and an insulating sheath layer formed outside the conductor. The insulating sheath layer includes a silane graft polymer as a main constituent. The silane graft polymer is formed by a graft-polymerization that an unsaturated silane compound and an organic peroxide are added to polyethylene, and is cross-linked contacting with water in the presence of a siloxane condensation catalyst. Alternatively, the insulating sheath layer includes a composition including polyethylene as a main constituent, and the composition is cross-linked by being irradiated with an ionizing radiation.
